OS X Snow Leopard Details

JD-1027 writes in to kick off a discussion of OS X Snow Leopard. Apple's stated goal: "Taking a break from adding new features, Snow Leopard — scheduled to ship in about a year — builds on Leopard's enormous innovations by delivering a new generation of core software technologies that will streamline Mac OS X, enhance its performance, and set new standards for quality." The technologies: Grand Central to get better use of multiple processors and multicore chips, OpenCL to tap the power of the GPU, 64 bit so we can finally have our 16 TB of RAM, QuickTime X for optimized modern codec performance, and built in Exchange support in iCal, Address Book, and Apple Mail that most likely will help get Macs into corporate environments. We've previously discussed ZFS in the server version of Snow Leopard."

But I don't remember hearing about anything like that from Apple, and now they want to charge for something we expected to be in there anyway?

      This is why no-one expects to pay for service packs. Can you imagine the uproar if MS charged for XP SP1/2/3?

      Um, since when are "stability and performance" considered "features"

      This seems to be a common failure to understand what Apple is claiming they will be adding in snow leopard. From TFA Apple will be adding... "...a new generation of core software technologies that will streamline Mac OS X, enhance its performance, and set new standards for quality."

      That is, they're adding new technology that will allow for increased performance and stability. An example of this is OpenCL, which will make it easier for software developers to make use of the GPU for miscellaneous computing tasks... thus increasing the performance of those applications. Another new technology is Grand Central, making it easier for developers to get the most out of multi-core processors, again increasing performance and also increasing stability. Yet a third example is the move to 64-bit to allow applications to address more memory, thus increasing performance. You'll note none of these are about fixing performance or stability bugs in OS X; although doubtless Apple will apply them to do that as well.

      I don't think I should have to shell out more money for "stability and performance" because they should have been included with Leopard, but obviously were not.

      Hey, if you don't like what is in snow leopard, no one is forcing you to pay for it. Just wait for the next release you do feel is worth the money. Still, I think you are misunderstanding the summary and the blurb. When Leopard was introduced one of the features allowed OpenGL applications to automatically spawn an extra thread to feed the GPU, utilizing a second core even for applications that had not been written to take advantage of it and providing significant performance improvements for many applications. This is more of the same, features being added to increase performance, not bugs being fixed to increase performance.

      You make it sound like "features" exist on some continuum, where you can always add more, but stability, security, and optimization are some binary quantities where the OS either has them or does not. If it doesn't, then you're getting ripped off. If they say they're going to improve the features of the OS, you say "OK, that's worth paying for," but if they say they're going to improve one of the other three things, than you take that as evidence hat it didn't have those to begin with. Why not say "whoa, why should I pay for new features- it's just admitting that there were useful features that should have been here in the last release."

      In reality, all four of these things exist on a continuum. OSX Leopard is very stable, hasn't had any serious security compromises in the wild, and isn't particularly slow either. It stacks up well against the competition. Yet, there have been things around before like BeOS- sure, it had its problems, but it was just blazingly, impressively fast, and it was beautifully, wonderfully responsive. OSX could be like that. And while OSX hasn't been the subject of major security exploits, researchers say the vulnerabilities are out there. And while it rarely kernel crashes, it certainly does sometimes.

      So Apple sells an OS with a nice, competitive feature set, great stability, apparently effective security, and decent optimization. They need to decide what to do with their developer time for the next release. If they concentrate on features, they can make approximately $300 million dollars off it in the first week of selling it. If they concentrate on making it super stable, blazingly fast and responsive, or having security like a hardened SELinux or OpenBSD installation, then the attitude is "Why didn't they do that already for free? I'm not paying for that."

      That attitude makes short-term profit motivation favor lots of new features with half-assed security, stability, and optimization. It takes someone visionary like Jobs to back of and say "look, we can't make a quick buck off this other stuff like we can some shiny new widgets, but these things have a big impact on user experience, which will affect the long-term viability of our platform, so we're spending money on it anyway."

      But if users would just consider features, security, stability, and optimization all as things worth paying for, there'd be a lot more competition to deliver them.

      Okay, now go read the linked description of snow leopard and show me where is says they're charging for making OS X more stable, instead of adding new technologies that make applications on top of OS X more stable and faster.


      Consumers don't make such hair-splitting distinctions. The consumer's view is that any aspect of the OS X that prevents applications from being perfectly stable constitutes a defect, and consumers don't like to pay for somebody else's mistake. Consumers would doubtless willing to pay for an upgrade that actually made the applications that they already have run perceptibly faster (which for most people means something like 20% or better) but it is hard to imagine that this is achievable.

      So if it is to be a full-price upgrade, Apple needs to have some sort of bonuses up its sleeve, such that the consumer who upgrades will perceive an immediate, easily perceptible benefit.

      UFS support doesn't work that well because Mac OS X was designed to support both of its ancestors: OpenStep and Mac OS 9. Mac OS 9 applications rely on resource forks, file and creator types and case preservation and insensitivity, and they were often quickly ported to Carbon. No one wants to reconsider their app's fundamentals just to get it to run on a new OS; if they did, maybe we'd have a cleaner solution today.

      Apple is moving towards ZFS, I just hope they'll start using it in Mac OS X client as well. All the neat features that *do* take up space (like revisions) and which people aren't used to can be easily turned off.

      Most of Apple's reconsiderations of UNIX have been made to simplify or streamline what's there. Take launchd, which is their daemon that replaces rc.d and the startup system surrounding it. It was built to work with programs as they worked today. Upstart in Ubuntu was developed to be an entirely new design and work better and as a consequence probably does not work with completely unaltered programs. Tell me honestly: do you think people wouldn't have ragged on Apple for "being Apple" if they had done Upstart instead of launchd?

      The problem isn't Apple making up new solutions to problems solved years ago, the problem is thinking these solutions can't be improved. Most (not all) of Apple's own problems in OS X with respect to being a UNIX citizen consists of compatibility junk that they're just now going to get around to dropping. (The newest version of Mac OS X manages to be certified as UNIX compliant, even if it's obviously not Linux certified since a different kernel is used.)

    I don't see why they would drop PPC support yet. Certainly, stripping PPC code from an Intel Mac doesn't make much difference to the disc space use. Mostly, stripping out unused languages makes much more difference. I gained 2.5GB of space on my MacBook Pro by doing so and I now have universal binaries that are very similar in size to those seen in Snow.

    They still have to maintain a port of Mac OS X just in case, and the also have to keep OS X running on the iPhone (Strong ARM) so I don't see the benefit of focussing just on Intel CPUs. In addition, keeping code running on PPC will help with keeping bugs down as it is often the case that just the act of compiling C code for a different architecture can result in unseen bugs showing up. As for performance tuning, rarely do you need to worry about much more than some small parts of the code to fine tune for a specific platform.

    I'm not surprised that this developer preview is Intel only but I will be surprised to see the final release be Intel only. Leopard on PPC could no doubt do with some fine tuning although it does run surprisingly well on my nearly five year old G4 iBook. Besides which, the last of the PPC machines were being sold by Apple as late as the end of 2006 (PowerMac G5s) so I think it would be a bad move for them to drop support this early.

    It's just the Apple mindset, and it's kind of ironic. Apple computers do tend to be well built, and last a good while, but Apple's stance seems to be that everyone should always be buying the latest and greatest, and that you should ALWAYS have their latest OS release.

    Look at software applications for example. Many of them already now require OS X 10.5 or newer. My PowerPC mac runs 10.4 and I have no intention of upgrading it, so I'm shut out of those applications completely (except for older versions). Windows software on the other hand: most stuff out there now will work at least as far back as Windows 2000. Not as much, but still a lot of stuff will work back to Windows 98 and some ever Windows 95.

    Basically just accept: if you want to be part of the Mac club, Apple expects you to be regularly dishing out cash for their stuff.

    For what it's worth, I do thoroughly enjoy using a Mac (though I have Windows and Linux systems too). I just am not happy being forced to move up from 10.4 to 10.5 when I didn't want to at the time.

    You see, this attitude of consumers is exactly why companies like Apple and Windows have so far focussed more on building OSes that look good, rather than work well. People want a shiny new thing, not a really efficient, rock solid operating system, because they have got used to crashes, useless error-messages, viruses and spam.

    For me, this is the most enthralling idea in the End-User computer market in years. Finally, a company decides it's time to stop adding new eye-candy. Instead, Apple is taking a step back and taking their time to iron out the bugs and add actual innovation.

    OpenCL sounds amazing. If it works as advertised, it will give developers who really care about performance the option to tap into the hugely parallel architecture available on the GPU that was inacessible to most of us so far (unless we wanted to learn the obscure proprietary semi-languages of ATI, IBM and nVidia).

    Grand Central seems to be just the opposite of this: It will make sure those eight cores we'll soon all have in our machines will actually get used, even if the developers who wrote the programs we run didn't care to think about parallelization.

Why are users' *losing* software and files so often that they need a *Finder*? Why are they so dependent on Spotlight that OS X might as well house all files in a flat-file-system?

I write graphics software for a living. Powerful graphics software, written at the metal level. I'm all for multicore/multiprocessor at the OS level; the easier, the better, and likewise, multi-machine for even bigger jobs.
